Oxalic acid is the most ubiquitous and common low molecular weight organic acid produced by living organisms. Oxalic acid is produced by fungi, bacteria, plants, and animals. The aim of this review is to give an overview of current knowledge about the microbial cycling of oxalic acid through ecosystems. Here we review the production and degradation of oxalic acid, as well as its implications in the metabolism for fungi, bacteria, plants, and animals. Indeed, fungi are well known producers of oxalic acid, while bacteria are considered oxalic acid consumers. However, this framework may need to be modified, because the ability of fungi to degrade oxalic acid and the ability of bacteria to produce it, have been poorly investigated. Finally, we will highlight the role of fungi and bacteria in oxalic acid cycling in soil, plant and animal ecosystems.
草酸是生物体产生的最普遍和常见的低分子量有机酸。草酸由真菌、细菌、植物和动物产生。本综述的目的是概述当前关于草酸通过生态系统进行微生物循环的知识。在这里，我们回顾了草酸的产生和降解，以及其在真菌、细菌、植物和动物代谢中的意义。事实上，真菌是草酸的主要生产者，而细菌则被认为是草酸的消费者。然而，由于真菌降解草酸的能力以及细菌产生草酸的能力尚未得到充分研究，这一框架可能需要进行修正。最后，我们将强调真菌和细菌在土壤、植物和动物生态系统中草酸循环中的作用。
